Leishmaniasis in Greece I. Isolation and identification of the parasite causing human and canine visceral leishmaniasis.

Three human and 19 canine leishmanial stocks were typed according to their excreted factor serotype and the electrophoretic mobility of their MDH, GPI, G6PDH and 6PGDH and shown to be identical with regard to these characters and, thus with Leishmania donovani infantum. This verifies the opinion of earlier researchers, who suggested that the parasites which cause human and canine visceral leishmaniasis in Greece are the same organism and that dogs are the reservoir for the human infection. The complexities raised by the co-existence of human cutaneous leishmaniasis in Greece caused by L. tropica (formerly L. t. minor) are stressed. A comparison was made of the clinical symptomatology, serological diagnosis by IFA and ELISA tests and parasitological diagnosis of the human cases and canine infections.
